Wikisource Plans Pricing
All Wikisource APIs — MediaWiki Action API, MediaWiki Core REST API, and the Wikimedia REST API v1 — are free of charge under the Wikimedia API usage guidelines. No registration, API key, or payment is required for read access. Write access (page edits, proofread-status updates) requires OAuth 2.0 via meta.wikimedia.org, which is also free. The only mandatory requirement is a contactable User-Agent header; violating usage guidelines or failing to identify your client may result in an IP block without notice.
